Keen Eye : This Pokémon cannot have its accuracy lowered. This ability does not prevent any accuracy losses other than stat modifiers, such as the accuracy cut from fog; nor does it prevent other Pokémon's evasion from making this Pokémon's moves less accurate. This Pokémon can still be passed negative accuracy modifiers through Heart Swap. Overworld: If the first Pokémon in the party has this ability, any random encounter with a Pokémon five or more levels lower than it has a 50% chance of being skipped.

Unnerve : Opposing Pokémon cannot eat held Berries while this Pokémon is in battle. Affected Pokémon can still use Bug Bite or Pluck to eat a target's Berry.

Big Pecks : This Pokémon's Defense cannot be lowered by other Pokémon. This Pokémon can still be passed negative Defense modifiers through Heart Swap or Guard Swap.
